Ok, I need some help here. I having problems implementing a DD Script (http://www.dynamicdrive.com/dynamici...tabcontent.htm) but the script isn't the problem.

The script is setup to use lists, see below:
HTML Code:
<ul id="tablist">
<li><a href="http://www.dynamicdrive.com" class="current" onClick="return expandcontent('sc1', this)">Dynamic Drive</a></li>
<li><a href="new.htm" onClick="return expandcontent('sc2', this)" theme="#EAEAFF">What's New</a></li>
<li><a href="hot.htm" onClick="return expandcontent('sc3', this)" theme="#FFE6E6">What's Hot</a></li>
<li><a href="search.htm" onClick="return expandcontent('sc4', this)" theme="#DFFFDF">Search</a></li>
</ul>
I'm trying to use this with table columns. I can get it to work in Internet Explorer with the code below but not in Mozilla:
HTML Code:
<ul id="tablist">
		<TD>
        <A HREF="#" onClick="return expandcontent('sc2', this)"

The code worked in evey browser before I modified the lists (removed the <li></li> tags). So I know that I need to get my table columns to act a lists or something like that. For some reason it won't work when I remove the table columns and place the <li></li> tags arround each <a></a> tag. Can anybody help me here?
